How to recover data from Promise Vess A2600 NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

Promise Vess A2600 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from Vess A2600.

Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Promise also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Can a failed RAID rebuild process lead to data loss on NAS Promise Vess A2600 devices?

Yes, a failed RAID rebuild process can potentially lead to data loss on NAS Promise Vess A2600 devices. During a rebuild process, data from the remaining drives in the RAID array is used to reconstruct the data on the failed drive. If there are any issues or errors during this process, it can result in incomplete or incorrect data being written to the new drive, leading to data loss or corruption. It is always recommended to have a backup of your data before performing any RAID rebuild operations.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS Vess A2600 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Promise Vess A2600. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

Vess A2600 has 16 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 1E;
  • RAID 3;
  • RAID 5;
  • RAID 6;
  • RAID 30;
  • RAID 50;
  • RAID 60;
  • JBOD;

NAS supports:

  • exFAT, VFAT, FAT 12 / 16 / 32;
  • NTFS / ReFS;
  • APFS / HFS+;
  • Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
  • VMFS / HikvisionFS;

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

  4. At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

Where are user’s files stored?

The Promise Vess A2600 network-attached storage keeps OS Linux operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

    Is it possible to recover data from a NAS Promise Vess A2600 device if the device is experiencing frequent disconnections or network errors?

    • Hetman Software 7.09.2023 20:00 #

      It is possible to recover data from a NAS Promise Vess A2600 device even if it is experiencing frequent disconnections or network errors. However, the success of data recovery depends on the specific issue causing the disconnections or errors.

      If the problem is related to network connectivity, you may try troubleshooting the network issues first. Ensure that all network cables are securely connected, check the network settings on the device, and verify that the network infrastructure is functioning correctly.

      If the frequent disconnections or network errors are due to hardware failure or other issues with the NAS device itself, it is recommended to contact Promise Technology support for assistance. They can provide guidance on troubleshooting steps or recommend professional data recovery services if necessary.

      In any case, it is always advisable to have regular backups of your important data to avoid data loss situations.
